Groove influence for golf irons and drivers

ABSTRACT

Grooves made for irons and drivers of golf clubs are adjusted so they will give a desirable rotation for the golf ball after impact. Beside the other possible adjustments that I mention, the grooves will primarily have one wall slanted to the other wall. This will allow the ball to release in a direction and or intensity level different than the standard grooves. In the United States Golf Association the golf irons and drivers have different rules and regulations than golf putters.

BACKGROUND OF THE INVENTION

The grooves in golf clubs are usually embedded into the face of the clubs straight in with the walls and the edges of the groove identical. The grooves of the club helps grip the golf ball on impact, which gives influence on how the ball will rotate in the air and the intensity of rotation. My invention will allow the ball rotate in a more favorable and a more predictable way. With the invention I kept in mind the rules and regulations of the United States Golf Association. Putters do have different rules and regulations.

BRIEF SUMMARY OF THE INVENTION

The invention primarily is to change the angle of the walls of the grooves. It may require changing only one wall angle or both wall angles depending on the intensity level wanted. The invention will also adjust if needed the radius of the edges of the groove points (where the clubface and the walls of the groove come together). This will offer adjusted resistance to influence the golf ball's rotation and intensity rotation in a more desired manner after the golf ball releases from the clubface at impact.

BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS

FIG. 1

This is a partial side view of the clubface and how the grooves are indented into the face of the club. For this example the walls of the grooves A-side is on top and B-side is on the bottom. “C” labels the flat part of the clubface.

FIG. 2

This is a partial side view of the face of the clubface with the B-Side wall of the groove of the club angled towards the A-Side wall. For this picture A-Side of the club is on top and B-side is bottom. A-Side and B-Side can be flipped.

FIG. 3

This is a partial side view of the face of the club with B-Side on top of A-Side. Changing A-Side and B-Side will reverse the influence.

FIG. 4

This picture is a partial side view of the groove. In this drawing you see the rounding edge and wall that would be on B-Side designated by a dashed line. The rounding radius (“D”) would have been set at the range from the largest as allowed by the USGA to the same size A-Side's rounded edge (“E”). A point from the beginning to the end of the possible rounding (“G” to “H”) is where the sloped edge would begin and go to A-Side's point “F”.

FIG. 5

This is partial side view that shows how the groove of the invention would look.

DETAILED DESCRIPTION OF THE INVENTION

The invention is to change the angle of the grooves in the face of the golf clubs of irons and drivers. This will allow the golf ball to rotate after impact in a favorable rotation direction or intensity. The standard grooves of the golf club are usually as similar to each other as possible. There will be two sides of the groove referred to as A-Side and B-Side. This invention will adjust the angle of one wall (B-Side) to reduce the resistance and the other wall (A-Side) will be at 90 degrees (or less) to offer more resistance. If the A-Side were less the wall would have an angle that would slope away from the B-Side. The B-Side will have an angle that will slope towards A-Side. This will influence the ball's rotation and intensity of the rotation.

This invention will also utilize the rounding of the edges where the groove walls meet the face of the club. The groove edges will be at least equal to each other (A-Side edge rounding =B-Side edge rounding). If not the A-side will have a smaller radius of rounding edge than B-Side. A-Side will have as small as a radius as possible and the B-Side will have a Radius as Large as possible. The starting point of the slope from B-Side to A-Side will be in between the beginning and the end of the rounding edge on the B-side. The end of the slope will be at the bottom of the A-Sides wall. The clubface will still have space in between each groove.

The less steep of an angle from one wall of the groove (B-Side) to another (A-Side) will offer less resistance of the golf ball to release from the club. The larger length of the A-Side wall will offers more resistance of the golf ball to release from the club. If A-Side wall is angled less than 90 degrees (away from B-Side) this will offer more resistance. The smaller of radius of the rounding on A-Side or B-side of the edges will offer more resistance. These factors being adjusted will influence the ball to release and rotate towards the less resistance side (B-Side) or the golf ball will release and rotate with not as much intensity of the more resistance side (the A-Side). (A-Side and B-Side can be rotated (flipped). They can be switched to get a different rotation or intensity of rotation. When describing the invention I kept in mind of USGA's rules and regulations. 

1. I claim that this invention will influence the rotation of the golf ball when struck by a golf iron or golf driver.
